任何 conda 或 pip 操作都会在 Windows 10 中出现 SSL 错误

Question

我尝试在 Windows 10 系统中安装或更新新软件包，其中安装了 Anaconda3（2019 版）。但每次我都会遇到相同的 SSL 错误。如果我可以在家庭 WiFi 网络中访问该网络，我会怀疑这可能是公司防火墙问题。但到处我都会遇到同样的错误。运行 COnda 搜索时，出现此错误：

conda search
Loading channels: failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/free/win-64/repodata.json.bz2>
Elapsed: -

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.

If your current network has https://www.anaconda.com blocked, please file
a support request with your network engineering team.

SSLError(MaxRetryError('HTTPSConnectionPool(host=\'repo.anaconda.com\', port=443): Max retries exceeded with url: /pkgs/free/win-64/repodata.json.bz2 (Caused by SSLError("Can\'t connect to HTTPS URL because the SSL module is not available."))'))

使用 Pip install 我收到此错误：

pip install keras

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

我从这个位置“ https://slproweb.com/products/Win32OpenSSL.html ”安装了 OpenSSL ，并在 PATH 变量中设置了 lib 文件夹。但没有任何作用。请建议。

Answer 1

我能够按照此说明解决问题。基本上： * 将以下文件从CONDA_PATH\Library\bin复制到CONDA_PATH\DLLs

libcrypto-1_1-x64.*
libssl-1_1-x64.*

Answer 2

在 Miniconda、Win11 Pro x64 上。想要创建一个新的环境，conda install pip突然遇到了同样的问题。

• 首先更新 conda update --all(base) 中的基础，然后再尝试conda install pip或再次尝试。

  没用

• 安装最新的 OpenSSL

  没用

• 将最新的 OpenSSL DLL 复制到 \bin 和 \DLLs 目录

  复制libcrypto-3-x64.dll+libssl-3-x64.dll

  从C:\Program Files\OpenSSL-Win64\bin

  到C:\Users\username\anaconda3\Library\bin

  并C:\Users\username\anaconda3\Library\DLLs

  没用

• 将现有 dll 从 \bin 复制到 \DLLs

  复制libcrypto-1_1-x64.dll并libssl-1_1-x64.dll

  从C:\Users\username\miniconda3\Library\bin

  到C:\Users\username\miniconda3\DLLs

  工作过

Answer 3

conda update conda

收集包元数据（current_repodata.json）：失败

CondaSSLError：OpenSSL 在此计算机上似乎不可用。下载并安装软件包需要 OpenSSL。

异常：HTTPSConnectionPool（主机='repo.anaconda.com'，端口=443）：超过最大重试次数，网址：/pkgs/main/win-64/current_repodata.json（由SSLError（“无法连接到HTTPS URL”）引起因为 SSL 模块不可用。"))

针对以上问题的解决方案：

1. 尝试使用 Anaconda powershell 提示符，如下图所示：

2.通过基础环境

A。conda activate base

b.conda update --all

笔记：

A。Conda 始终创建默认环境作为基础。我们可以激活基础环境来升级conda。
